Bar's Leaks Axle and Differential Gear Repair, 16.9 Oz

My girlfriend has an 08 rav4 that had a leaky rear axle seal and viscous coupler. The leaks were both fairly small but within a month the differential would be down to about half full which made me very weary whenever she had to go somewhere. The last thing I would want is to put a rear diff in her car. I typically don't trust these stop leak type of products because in my experience they're usually just snake oil. I read the reviews and figured I had nothing to lose so I tried it out. I must say this stuff is amazing, I added just a little bit over the recommended amount to the rear diff and 2 months later the fluid is still full. I often look under the car to check for drips and there is never a drop. There used to be small drops of gear oil hanging off of the diff about to fall onto the ground but this has completely stopped. You can still see where a very negligible amount of gear oil is leaking down the side of the diff below the seals so I don't think the leaks have stopped 100% but more realistically they've probably stopped about 90-95%. This additive is probably more of a temporary fix because leaking seals usually get worse over time but it's gotten me 2 months without having to pull cv axles and replace the seals so I am very pleased. I cannot speak on the gear repair or ability to stop noisy rear axles that this product claims because I didn't have that issue but it's ability to stop leaks seems to be great. I had very slow leaks and it did well for me but I doubt this stuff would help with more serious leaks. Overall I think this is a great product! Quality: 10/10 Price: 10/10 Leak repair: 9.8/10

I had a small leak on a Kawasaki 4x4 ATV. Added about 6oz to the rear diff, and it solved my issue the same day after about a 30 min ride and spray down with brakleen. Zero drips for the last week or so Seems to have worked perfect and performs as advertised. Actually pretty impressed. Was planning on doing a full labor intensive rebuild, but took a chance on this. We will see how long it lasts, but so far so good!

my rear pinion bearing was bad and leaking it fixed the leaking unfortunately the bearing had been leaking so long i needed a new one but it reduced the noise of the bad bearing by quit a bit. I was able to get a couple of thousand miles out of the bad bearing before I had it changed. I didnt follow the recommendations I didnt mix this stuff I put all four quarts in and I think i use a little bit of the recommended oil just to fill the diff. It will fix a seal but it aint gonna fix a bad bearing. So its a temp fix if anything. After I had my bearing replaced I filled it up with this stuff.

Rear axle seal leaks are slowly disappear will get to replace the seals just got other priorities first

This is amazing stuff. I’m impressed. Had a leak on my 2013 Jeep Rubicon rear Dana 44 sealed it up almost immediately it was just barely weeping, but it is totally dry now. Left rear seal pretty good stuff.

Did not work for my Polaris side by side

It did stop the leak in my differential

Work says it should

Works well

I had a very small oil leak from the gearbox, about 4-5 drops per day. First I tried Xado stop gearbox leak - no effect, then I tried Lique molly stop gearbox leak - the leak decreased, but 2-3 drops remained per day. Now I changed the oil with new one and put this Bars additive. After 2 days of driving the leak stopped, there is not a single drop on my garage floor! So this works, and the gearbox shifts better. I am satisfied!
